In order to prevent overcharging of the battery, it is necessary to control the charging endpoint. When the battery is fully charged, there are some special information that can be used to determine whether the charging has reached the endpoint. There are generally six methods to prevent the battery from being overcharged:

01) Peak voltage control: Determine the charging endpoint by detecting the peak voltage of the battery;

02) dT/dt control: Determine the charging endpoint by detecting the rate of change in battery peak temperature;

03) △ T control: When the battery is fully charged, the difference between temperature and ambient temperature will reach its maximum;

04) - △ V control: When the battery is fully charged and reaches a peak voltage, the voltage will decrease by a certain value;

05) Timing control: Control the charging endpoint by setting a certain charging time, generally setting the time required to charge 130% of the nominal capacity to control;
